TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames. NO contact with hot surfaces.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention if skin irritation occurs. 
Eyes Redness. Pain. Severe burns.  Wear safety goggles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Sore throat. Headache. Nausea. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer immediately for medical attention. 

SPILLAGE DISPOSAL

Physical dangers
 

Chemical dangers
Decomposes on heating or on burning and on contact with hot surfaces. This produces toxic and corrosive gases including phosgene (see ICSC 0007) and hydrogen chloride (see ICSC 0163). The solution is a weak acid. Attacks many metals in the presence of water. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (not established):. 

Routes of exposure
The substance can be absorbed into the body by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is corrosive to the eyes. The substance is irritating to the skin. 

Effects of long-term or repeated exposure
The substance may have effects on the kidneys. This may result in tissue lesions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 117-118°C
Relative density (water = 1): 1.4
Solubility in water: none
Octanol/water partition coefficient as log Pow: 3.43
Vapour pressure: negligible
Flash point: 204°C o.c. 
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Other melting points: (technical grade) 114°C.
Depending on the degree of exposure, periodic medical examination is suggested.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
